We need to improve the render speed of our map based on WMS service from the French Institute ign.frWe tried to use the WMTS service (https://geoservices.ign.fr/documentation/geoservices/wmts.html), but according to mapsuite support, it's not possible du to an issue in the SupportedCRS representation.

The GetCapability contains IGNF:LAMB93 instead of something like this urn:ogc:def:crs:EPSG::2193

My main concern is that others tools on the market are able to open this WMTS service without crashing. Is there anything I can do to open this WMTS in mapsuite ?
